Compression Collar

This model was inspired by an umbrella that spins in the wind because the clamping screw is rusted in place, the umbrella post is loose in the stand, and I just wanted something simple to help hold it in place better. 

I saw someone else's parametric model for the umbrella stand adapter, but I didn't think it would do the job I needed. So I collaborated with ChatGPT and learned a lot about parametric modeling. Behold the compression collar! 

This works way better than I originally imagined, although I haven't yet fully weather tested it. But it does a great job of gripping the post through the simple compression design. 

It would probably be stronger printed on an angle with a support, but I don't think the cutouts would be as well defined, and the visible part of the collar looks better this way :)

PETG would probably be better for most applications, but I printed this in PLA silk and functionally it works.
